The two most terrible things about cryptocurrency trading are: 1. When the market is over, you are still obsessed and unwilling to leave. In the end, when the banquet is over, you have to pay the bill; 2. You think it is a rebound, but it is actually a reversal. You want to prove that you are a Zhuge Liang, but you are repeatedly slapped in the face by the market. How to avoid the above two situations? In fact, the answer is two words, rules. The rules can be very simple. For example, the 10-day moving average is used as the basis for advance and retreat. As long as it does not effectively fall below the 10-day moving average, it is enough. If it falls below, clear the position. If it falls below and cannot be recovered the next day, go short. Don't calculate whether it will fall below, don't calculate when it will fall below, let alone explain why it falls below. We are just the guardians of the rules. The price I have to pay is to sell it when it falls below the false price, and then buy it back when it meets the conditions, which increases the transaction cost. The benefit is that you will never be trapped and you will never miss the opportunity. Everything has a price. It depends on whether you think it is worth it. You can set one or two moving averages. More means more, less means more. Don't look at support when the market falls. If you can't recover after breaking a certain moving average, you need to be on guard against risks. You can't say which moving average is supporting you. Don't look at support when the market falls. When you find that all the moving averages are not supporting you, you will die. There are many moving averages, but you only have one life. Therefore, it is best to have only one moving average, because you only have one life. Don't look at support when the market falls, but look at support when the market rises. As long as the daily moving average is still there and the K line has not fallen below, you should stick to long positions. What is growth and growth? It means finding problems, facing them, thinking about them, solving them, and trying to prove that you have no problems. These are all market problems. This is the biggest problem.
